Question

我对Unity感到陌生（从几天前开始）。

我正在尝试创建一种功能，使相机始终跟随滚球，但是在保持聚焦于主要对象的同时，也应通过箭头键控制相机。

我有以下代码跟随实际对象：

using UnityEngine;

public class FollowPlayer : MonoBehaviour {

    public Transform player;
    private Vector3 offset = new Vector3(0, 3, -5);

    // Update is called once per frame
    void Update() {
        transform.position = player.position + offset;
    }
}

上面的代码工作完美，它随对象移动而移动。

但是我尝试了以下方法来移动相机：

using UnityEngine;

public class FollowPlayer : MonoBehaviour {

    public Transform player;
    public GameObject MainCamera;
    public Vector3 offset = new Vector3(0, 3, -5);

    private Vector3 RotateOffset;
    public float rotateJump = 1f;

    // Update is called once per frame
    void Update() {

        //Rotate Camera 90 degrees Left
        if (Input.GetKey("left")) {
            RotateOffset = new Vector3(transform.position.x - rotateJump, 0, transform.position.z - rotateJump);
            transform.position = player.position + RotateOffset;
        }

        //Rotate Camera 90 degrees Right
        if (Input.GetKey("right")) {
            RotateOffset = new Vector3(transform.position.x + rotateJump, 0, transform.position.z + rotateJump);
            transform.position = player.position + RotateOffset;
        }
    }
}

但这只会将相机从位置A沿直线移动到位置B，如下所示，而不会旋转：

位置A：

位置B：

如何让相机跟随物体并仍由用户控制？

谢谢！

我在板上移动对象的代码如下：

using UnityEngine;

public class PlayerMovement : MonoBehaviour {

    public Rigidbody rb;
    public float MovementForce = 200f;

    void FixedUpdate() {
        //Move Forward
        if (Input.GetKey("w")) {
            rb.AddForce(0, 0, MovementForce * Time.deltaTime);
        }

        //Move Left
        if (Input.GetKey("a")) {
            rb.AddForce(-MovementForce * Time.deltaTime, 0, 0);
        }

        //Move Back
        if (Input.GetKey("s")) {
            rb.AddForce(0, 0, - MovementForce * Time.deltaTime);
        }

        //Move Right
        if (Input.GetKey("d")) {
            rb.AddForce(MovementForce * Time.deltaTime, 0, 0);
        }
    }
}

编辑：

我更新了FollowPlayer脚本，如下所示：

using UnityEngine;

public class FollowPlayer : MonoBehaviour {

    public Transform player;
    private Vector3 offset = new Vector3(0, 3, -5);

    private float RotateVal = 2f;

    private Vector3 VPanAmount = new Vector3(2, 0, 0);
    private Vector3 HPanAmount = new Vector3(0, 2, 0);

    private Vector3 VRotatoinOffset;
    private Vector3 HRotatoinOffset;

    private void Start() {

    }

    // Update is called once per frame
    void Update() {

        if (Input.GetKey("left")) {
            VRotatoinOffset = player.position + offset - VPanAmount;
            transform.Rotate(0, -RotateVal, 0);
        }

        if (Input.GetKey("right")) {
            VRotatoinOffset = player.position + offset + VPanAmount;
            transform.Rotate(0, RotateVal, 0);
        }

        if (Input.GetKey("up")) {
            HRotatoinOffset = player.position + offset + HPanAmount;
            transform.Rotate(-RotateVal, 0, 0);
        }

        if (Input.GetKey("down")) {
            HRotatoinOffset = player.position + offset + HPanAmount;
            transform.Rotate(RotateVal, 0, 0);
        }

        transform.position = player.position + offset - VRotatoinOffset - HRotatoinOffset;
    }
}

摄像机会随着对象的移动而旋转和移动，但是摄像机的焦点不会停留在对象上，并且摄像机会跳到运动场以下。

Unity 2018 Camera跟随对象，但使用箭头键平移
